DETAILED DESCRIPTION

The terms “a” or “an”, as used herein, are defined as one or more thanone. The term “plurality”, as used herein, is defined as two or morethan two. The term “another”, as used herein, is defined as at least asecond or more. The terms “including” and/or “having”, as used herein,are defined as comprising (i.e., open language). Reference throughoutthis document to “one embodiment”, “certain embodiments”, “anembodiment”, “an implementation”, “an example” or similar terms meansthat a particular feature, structure, or characteristic described inconnection with the embodiment is included in at least one embodiment ofthe present disclosure. Thus, the appearances of such phrases or invarious places throughout this specification are not necessarily allreferring to the same embodiment. Furthermore, the particular features,structures, or characteristics may be combined in any suitable manner inone or more embodiments without limitation.

According to an embodiment, the present disclosure relates toaugmentation of a digital user experience. The augmentation may includean overlaying of digital objects onto a viewable display area of adisplay of an electronic device. The electronic device may be a mobiledevice such as a smartphone, tablet, and the like, a desktop computer,or any other electronic device that displays information. The digitalobjects may include text, images, videos, and other graphical elements,among others. The digital objects may be interactive. The digitalobjects may be associated with third-party software vendors.

In order to realize the augmentation of a digital user experience, areference patch, that is a region of interest acting as an anchor, canbe used. In one embodiment, the reference patch or other visuallydetectable element may serve to indicate a position at which digitalcontent is to be placed onto a display. In some embodiments and asdescribed herein, the reference patch may include encoded informationthat may be used to retrieve digital content and place that digitalcontent into a desired location or locations in displayed data. Thereference patch can be embedded within displayed data (such as, but notlimited to, an image, a video, a document, a webpage, or any otherapplication that may be displayed by an electronic device). Thereference patch can include unique identifying data, a marker, orencoding corresponding to predetermined digital content. The referencepatch can indicate to the electronic device the particular content thatis to be displayed, the position at which the content is to be placed,and the size with which the content is to be displayed. Accordingly,when a portion of the displayed data including the reference patch isvisible in a current frame of displayed data, the corresponding contentcan be overlaid on the current frame of the displayed data.

The above-described augmentations are particularly relevant toenvironments where the underlying content is static. Static content mayinclude textual documents or slide decks. Often, the static content isstored locally in the electronic device. Due to its nature, the staticcontent is not capable of being dynamically adjusted according tocomplex user interactions, in real-time, during a user experience. Sucha digital user experience is cumbersome and inefficient. Thus, aheightened, augmented user experience is desired to provide increasedconvenience, engagement, and agility. The augmentations described hereinreduce cumbrousness by providing a visual representation/aid ofretrieved external digital content, and provide improved engagement ofthe user, agility of navigation through the displayed data, and overallperformance of the user device.

Described herein is a device and method to incorporate a reference patchwith encoded identifier attributes, where the reference patch serves asa conduit for delivering content into the displayed data.

Referring now to the figures, FIG. 1 is a schematic view of anelectronic device, such as a client/user device (a first device 701)communicatively connected, via a network 851, to a second electronicdevice, such as a server (a second device 850), and a generating device1001, according to an embodiment of the present disclosure. Further, inan embodiment, additional client/user devices can be communicativelyconnected to both the first device 701 and the second device 850. Asecond client/user device (a third device 702) can be communicativelyconnected to the first device 701 and the second device 850. As shown, aplurality of the client/user devices can be communicatively connectedto, for example, an Nth user device 70 n.

An application may be installed or accessible on the first device 701for executing the methods described herein. The application may also beintegrated into the operating system of the first device 701. The firstdevice 701 can be any electronic device such as, but not limited to, apersonal computer, a tablet pc, a smart-phone, a smart-watch, anintegrated AR/VR (Augmented Reality/Virtual Reality) headwear with thenecessary computing and computer vision components installed (e.g., acentral processing unit (CPU), a graphics processing unit (GPU),integrated graphics on the CPU, etc.), a smart-television, aninteractive screen, a smart projector or a projected platform, an IoT(Internet of things) device or the like.

As illustrated in FIG. 1, the first device 701 includes a CPU, a GPU,and a frame buffer, among other components (discussed in more detail inFIGS. 6-8). In an embodiment, the first device 701 can call graphicsthat are displayed on a display. The graphics of the first device 701can be processed by the GPU and rendered in scenes stored on the framebuffer that is coupled to the display. The CPU can have an associatedCPU memory and the GPU can have an associated video or GPU memory. Theframe buffer may be an allocated area of the video memory. It can beunderstood that the CPU may have multiple cores or may itself be one ofmultiple processing cores in the first device 701. The CPU can executecommands in a CPU programming language such as C++. The GPU can executecommands in a GPU programming language such as HLSL. The GPU may alsoinclude multiple cores that are specialized for graphic processingtasks. Although the above description was discussed with respect to thefirst device 701, it is to be understood that the same descriptionapplies to the other devices (701, 702, 70 n, and 1001) of FIG. 1.Although not illustrated in FIG. 1, the second device 850 can alsoinclude a CPU, GPU, and frame buffer.

FIG. 2A is a flow chart for a method 200 of generating a reference patchand embedding the reference patch into displayed data, according to anembodiment of the present disclosure. The present disclosure describesgeneration of the reference patch and embedding of this patch into thedisplayed data content in order to integrate additional content on thefirst device 701. In an embodiment, the first device 701 can incorporatedigital content into what is already being displayed (displayed data)for a more immersive experience.

In this regard, the first device 701 can generate the reference patch instep 205. The reference patch can be an object having an area and shapethat is embedded in the displayed data at a predetermined location inthe displayed data. For example, the reference patch can be a squareoverlayed and disposed in a corner of a digital document (an example ofdisplayed data), wherein the reference patch can be fixed to apredetermined page for a multi-page (or multi-slide) digital document.The reference patch can thus also represent a region of interest in thedigital document. The reference patch can be an object that, when not ina field of view of the user, is inactive. The reference patch can, uponentering the field of view of the user, become active. For example, thereference patch can become active when detected by the first device 701in the displayed data. When active, the reference patch can retrievedigital content and augment the displayed data by incorporating theretrieved digital content into the displayed data. Alternatively, thereference patch can become active when being initially located withinthe frame of the screen outputting the displayed data. For example, evenif another window or popup is placed over top of the reference patch,the reference patch may continue to be active so long as the referencepatch remains in the same location after detection and the windowincluding the document incorporating the reference patch is notminimized or closed. As will be described further below, the referencepatch can have a predetermined design that can be read by the firstdevice 701, leading to the retrieval and displaying of the digitalcontent.

In an embodiment, the first device 701 can use a geometrical shape forthe reference patch for placement into any displayed data usingapplications executed in the first device 701. The reference patch cantake any shape such as a circle, square, rectangle or any arbitraryshape. In step 210, the reference patch can also have predeterminedareas within its shape for including predetermined data. Thepredetermined data can be, for example, unique identifiers thatcorrespond to a surface area of the displayed data. The uniqueidentifiers can be, for example, a marker. As will be described below,the marker can take the form of patterns, shapes, pixel arrangements,pixel luma, and pixel chroma, among others. The surface area, by way ofthe unique identifiers, can be associated with predetermined digitalcontent that is recalled and displayed at the corresponding surface areain the displayed data. The unique identifier can include encoded datathat identifies the digital content, a location address of the digitalcontent at the second device 850 (see description below), a screenposition within the surface area at which the digital content isinsertable in the displayed data, and a size of the digital content wheninserted in the displayed data (adjustable before being displayed).

That is, in an embodiment, the surface area (or an available area inwhich digital content is insertable/to be inserted) of the displayeddata can be portion(s) of the displayed data that do not include objectsthat might obscure the reference patch or the digital content displayedat the corresponding surface area in the displayed data. For example,the first device 701 can use computer vision (described below) to detectthe objects. For example, a slide in a slide deck can include text,pictures, logos, and other media, and the surface area can be the blankspace or spaces around the aforementioned objects. Thus, the digitalcontent can be displayed somewhere in the blank spaces. In anembodiment, the surface area of the displayed data can include portionsof the displayed data that already include objects and the digitalcontent can be displayed at the same location as the objects. Forexample, a slide in a slide deck can include a picture of a user, andthe reference patch can be the area representing a face of the user andthe digital content can be displayed at the same location as a body ofthe user. For example, a slide in a slide deck can include an image of avehicle and the reference patch can be disposed in a blank space of thedisplayed data, while the digital content retrieved (e.g., a new carpaint color and new rims) can be displayed over the image of thevehicle. In other words, the digital content may be placed in a blankarea of the displayed data and/or in an area that is not blank (i.e., anarea that includes text, image(s), video(s), etc.).

In step 215, the first device 701 can embed the reference patch into thedisplayed data, such as a word processing document file (i.e., DOC/DOCX)provided by e.g., Microsoft® Word, in a Portable Document Format (PDF)file such as the ones used by Adobe Acrobat®, in a Microsoft® PowerPointpresentation (PPT/PPTX), or in a video sequence file such as MPEG, MOV,AVI or the like. These file formats are illustrative of some file typeswhich a user may be familiar with; however, applications included in thefirst device 701 are not limited to these types and other applicationsand their associated file types are possible.

The reference patch (or similar element) can be embedded into anydisplayed data, where the displayed data may be generated by anapplication running on or being executed by the first device 701. Thereference patch can encompass the whole area designated by the displayeddata, or just a portion of the area designated by the displayed data.The method of generating the reference patch and embedding the referencepatch into the displayed data has been described as being performed bythe first device 701, however, the second device 850 can instead performthe same functions. In order to be detected in the displayed data on thefirst device 701, the reference patch may only be simply displayed as animage on the screen. The reference patch may also simply be a rasterimage or in the background of an image. The reference patch is also ableto be read even when the image containing the reference patch is lowresolution. Because the reference patch is encoded in a hardy andenduring manner such that even if a portion of the reference patch iscorrupted or undecipherable, the reference patch can still be activatedand used.

In an embodiment, the reference patch can be embedded inside of a bodyof an email correspondence. The user can use any electronic mailapplication such as Microsoft Outlook®, Gmail®, Yahoo®, etcetera. As theapplication is running on the first device 701, it allows the user tointeract with other applications. In an embodiment, the reference patchcan be embedded on a video streaming or two-way communication interfacesuch as a Skype® video call or a Zoom® video call, among others. In anembodiment, the reference patch can be embedded in displayed data formulti-party communication on a live streaming interface such as Twitch®.

One way in which the first device 701 may embed the reference patch intothe displayed data is by arranging the generated reference patch in thedisplayed data such as in a desired document or other media. Thereference patch may include a facade of the digital content whichbecomes an integrated part of the displayed data. The facade can act asa visual preview to inform the user of the digital content linked to thereference patch. The facade can include, for example, a screenshot of avideo to be played, a logo, an animation, or an image thumbnail, amongothers. The facade can be a design overlay. The design overlay can be apicture that represents the underlying digital content superimposed overthe reference patch. In an embodiment, the facade can indicate thecontent that is represented by the reference patch. The facade can becontained within the shape of the reference patch or have a dynamicsize. For example, attention of the user can be brought to the facade byadjusting the size of the facade when the reference patch is displayedon the display. The adjustment of the size of the facade can also bedynamic, wherein the facade can enlarge and shrink multiple times. Bythe same token, a position and rotation of the facade can also beadjusted to produce a shaking or spinning effect, for instance.

Unlike traditional means of sending displayed data, the first device 701may not send the whole digital content with a header file (metadata) anda payload (data). Instead, the reference patch that may include a facadeof the underlying digital content is placed within the displayed data.If a facade is used, it indicates to the first device 701 that thesurface area can have digital content that can be accessed withselection (clicking with a mouse, touchpad, eye-gaze, eye-blinks, or viavoice-command) of the facade. The digital content can also be accessedor activated automatically, e.g., when the user has the reference patchdisplayed on the display of the first device 701. Other symbolic meansof visualization can be employed to indicate to the user that thesurface area is likely to include information for obtaining digitalcontent. For example, a highlighting effect can be applied along aperimeter of the reference patch in a pulsating pattern of highlightingintensity to bring attention to the presence of the reference patch. Forexample, a series of spaced dashes surrounding the reference patch andoriented perpendicular to the perimeter of the reference patch canappear and disappear to provide a flashing effect. Other means can beemployed to indicate to the user that the surface area is likely toinclude information for obtaining digital content, such as an audio cue.

The first device 701 employs further processes before embedding thereference patch into the displayed data. These processes and schemas arefurther discussed in FIG. 2B.

FIG. 2B is a flow chart of a sub-method of generating the referencepatch, according to an embodiment of the present disclosure. The firstdevice 701 can associate the digital content with the surface areacorresponding to the reference patch (e.g., via the unique identifiersincluded therein) generated by the first device 701. In an embodiment,the surface area may encompass the whole of the displayed data or aportion of it.

The reference patch, which includes the unique identifiers correspondingto the surface area associated with the digital content, is thenembedded into the displayed data by the first device 701. In some usecases, the displayed data including the reference patch can be sent ortransmitted to a second user having the third device 702 including thesame application, which then allows the second user to accessinformation within the surface area and obtain the digital content andhave it viewable on the third device 702. That is, the third device 702can have the same displayed data overlaid with the augmenting digitalcontent on the surface area of the display of the third device 702 inthe location or locations defined by the reference patch.

In FIG. 2B, the generating device 1001 uses additional processes toeffectuate generation of the reference patch which is obtained andembedded by the first device 701. In an embodiment, the generatingdevice 1001 encodes the reference patch with the unique identifierscorresponding to the surface area in step 205 a. The generating device1001 can mark areas of the reference patch in step 205 b to form themarker that, either separately or in combination, define or may be usedto access the unique identifiers. The marker can take the form ofpatterns, shapes, pixel arrangements, or the like. In an example, themarker can have a shape that corresponds to the shape of the surfacearea. In an example, the marker can have a size that corresponds to thesize of the surface area. In an example, the marker can have a perimeterthat corresponds to the perimeter of the surface area. The marker canuse any feasible schema to provide identifying information thatcorresponds to the surface area within parts of the displayed data. Inan embodiment, the marker can incorporate hidden watermarks that areonly detectable by the first device 701 and the third device 702, whichhave detection functionality implemented therein, for example having theapplication installed or the functionality built into the operatingsystem.

The marker can incorporate patterns which can then be extracted by thefirst device 701. In an example, the first device 701 can perform theembedding, then send the digital content having the embedded referencepatch to the third device 702. The encoding is performed by thegenerating device 1001 and may use any variety of encoding technologiessuch as the ARUCO algorithm to encode the reference patch by marking thereference patch with the marker. The first device 701 may also be usedas the generating device 1001.

In an embodiment, the marker can be comprised of a set of points,equidistant from each other and/or some angle apart from a referencepoint, such as the center of the reference patch or represent some otherfiducial points. That is, the fiducial points corresponding to themarker can provide a set of fixed coordinates or landmarks within thedigital content with which the surface area can be mapped relative tothe fiducial points. In an embodiment, the marker can be comprised of aset of unique shapes, wherein predetermined combinations of the uniqueshapes can correspond to a target surface area (or available area, orareas) for displaying the displayed data. The predetermined combinationsof the unique shapes can also correspond to predetermined digitalcontent for displaying in the surface area. The predeterminedcombinations of the unique shapes can also correspond to/indicate aposition/location where the digital content should be displayed at thesurface area relative to a portion of the surface area. A combination ofthe set of points and unique identifiers can be used as well.

For example, the unique identifiers can be unique shapes that correlateto predetermined digital content as well as indicating where the digitalcontent should be overlayed on the display (the screen position)relative to a set of points marked on the reference patch. The uniqueidentifiers can also indicate a size of the digital content to beoverlayed on the display, which can be adjustable based on the size ofthe surface area (also adjustable) and/or the size of the display of thefirst device 701. The unique identifiers can be relatively invisible orundetectable to the user, but readable by the first device 701 and coverpredetermined areas of the reference patch. The unique identifiers, andby extension, the marker, can have an appearance that is marginallydifferent from an appearance of the area of the reference patch. Forexample, the area of the reference patch can appear white to the userand the unique identifiers can also appear white to the user but mayactually have a slightly darker pixel color that can be detected andinterpreted by a device, such as the first device 701. For instance, theappearance of the unique identifiers can be 0.75% darker than the whitecolor of the area of the reference patch. Such a small difference can beidentified and discerned by the first device 701 while beingsubstantially imperceptible to the user.

In an embodiment, the area of the reference patch can be divided intopredetermined shapes, for instance a set of squares, and within eachsquare, the marker (such as a “letter”) can be included. For example,there can be 16 squares. Furthermore, subsets of the set of squares canbe designated to represent varying information, such as a timestampcorresponding to 8 of the squares, a domain corresponding to 5 of thesquares, a version corresponding to 1 of the squares, and additionalinformation corresponding to a remainder of the squares. Anidentification based on the set of squares can be, for example, an18-character (or “letter”) hexadecimal. The set of squares can furtherinclude additional subsets for a randomization factor, which can be usedfor calculating a sha256 hash prior to encoding the reference patch withthe hash. Together, the set of squares having the marker includedtherein can comprise the unique identifiers.

Moreover, the generating device 1001 can also employ chroma subsamplingto mark attributes represented by a particular pattern. In anembodiment, the generating device 1001 can mark parts of the referencepatch with predetermined patterns of pixel luma and chroma manipulationthat represent a shape, a size, or a position of the surface area fordisplaying the digital content. Moreover, the generating device 1001 canmark a perimeter of the reference patch with a predetermined edgingpattern of pixel luma and chroma manipulation that represents aperimeter of the surface area for displaying the digital content.

The generating device 1001 can further link the surface area with uniqueidentifiers in step 205 c. The unique identifiers can be hashed values(such as those described above) that are generated by the generatingdevice 1001 when the reference patch is generated (such as the onehaving the area of the reference patch divided into the subset ofsquares).

FIG. 2C is a flow chart of a sub-method of associating the surface areawith digital content, according to an embodiment of the presentdisclosure. In FIG. 2C, the generating device 1001 uses additionalprocesses to associate the surface area with digital content. In anembodiment, the generating device 1001 can associate the uniqueidentifiers corresponding to the surface area with metadata. In step 210a, the unique identifiers can be associated with metadata embodyinginformation about the storage and location of the digital content.Moreover, in step 210 b, the generating device 1001 can associate theunique identifier of the surface area with metadata which embodiesinformation about the format and rendering information used for thedigital content. In step 210 c, the generating device 1001 can associatethe unique identifiers of the surface area with metadata which embodiesaccess control information of the digital content.

In an embodiment, the storage of the digital content can be on a remoteserver, such as the second device 850, and the location of the digitalcontent can be the location address of the memory upon which it isstored at the remote server. The storage and location of the digitalcontent are thus linked with the metadata that can point to where thedigital content can later be obtained from. The digital content is notembedded into the displayed data. In an embodiment, the format andrendering information about the digital content is embodied in themetadata and associated with the unique identifiers. This information ishelpful when the first device 701 or the third device 702 are on thereceiving end of the transmitted displayed data and need to properlyretrieve and process the digital content.

Moreover, in an embodiment, the access control of the digital contentcan also be encompassed in the metadata and associated with the uniqueidentifiers corresponding to the surface area. The access control can beinformation defining whether the digital content can be accessed bycertain individuals or within a certain geographical location. Theaccess control information can define restrictions such as those placedupon time and date as to when and how long the digital content can beaccessed. The access control information can define the type of displayreserved for access by the first device 701. For example, a user maywish to restrict access to the digital content to certain types ofdevices, such as smartphone or tablets. Thus, the metadata defining adisplay requirement would encompass such an access control parameter.

FIG. 2D is a flow chart of a sub-method of integrating the referencepatch into the displayed data, according to an embodiment of the presentdisclosure. In FIG. 2D, the generating device 1001 uses additionalprocesses to effectuate integration of the reference patch into thedisplayed data. In an embodiment, the first device 701 can temporarilytransfer or store the reference patch in a storage of the first device701 in step 215 a. The storage can be accessed by the first device 701for embedding the reference patch into the displayed data at any time.The first device 701 can extract the reference patch from the storagefor embedding purposes in step 215 b. The first device 701 can alsoarrange the reference patch at a predetermined location and with apredetermined reference patch size in step 215 c. The first device 701can further embed the reference patch such that a document, for example,having the reference patch embedded therein can be sent to a recipient,for example the second user using the third device 702, where he/she canaccess the document using the application on the third device 702 asfurther described below. Again, the features of the generating device1001 can be performed by the first device 701.

The displayed data can be output from a streaming application or acommunication application with a data stream having the reference patchembedded therein. The actual digital content may not be sent along withthe underlying displayed data or data stream, but only the uniqueidentifier and/or a facade of the digital content is sent. The uniqueidentifier and/or the underlying metadata can be stored in a cloud-baseddatabase such as MySQL which can point to the second device 850 or acloud-based file hosting platform that ultimately houses the digitalcontent. No limitation is to be taken with the order of the operationdiscussed herein; such that the sub-methods performed by the firstdevice 701 can be carried out synchronous to one another, asynchronous,dependently or independently of one another, or in any combination.These stages can also be carried out in serial or in parallel fashion.

FIG. 3A is a flow chart for a method 300 of identifying the referencepatch included in the displayed data and overlaying the digital contentinto displayed data, according to an embodiment of the presentdisclosure. In an embodiment, in step 305, the first device 701 caninspect the stream of data being outputted by the first device's 701video or graphics card and onto the display of the first device 701.That is, the first device 701 can access a frame buffer of the GPU andanalyze, frame by frame, in the frame buffer, the outputted stream ofdata which can include the displayed data. In an embodiment, a framerepresents a section of the stream of the displayed data that is beingdisplayed by the first device 701. In that regard, the first device 701can inspect the outputted stream of data. The first device 701 canachieve this by intercepting and capturing data produced from the firstdevice 701's video card or GPU that is communicated to the first device701's display.

In an embodiment, in step 310, the first device 701 can processattributes of each pixel included in a single frame and detect groups ofpixels within that frame, which may have a known predetermined patternof pixel luma and chroma manipulation, in order to find the referencepatch.

The inspected frame by frame stream of data is also used by the firstdevice 701 to identify the reference patch which includes the uniqueidentifiers therein. In an embodiment, the first device 701 employspattern recognition algorithms to detect and identify the referencepatch, the perimeter of the reference patch, and/or the area of thereference patch. In an embodiment, the first device 701 detects andidentifies the reference patch via the marker itself. A variety ofpattern recognition algorithms can be used, such as Artificial NeuralNetworks (ANN), Generative Adversarial Networks (GAN), thresholding, SVM(Support Vector Machines) or any classification and pattern recognitionalgorithm available conducive to computer vision. Computer visiontechniques may be artificial intelligence techniques that traincomputers to interpret and understand a visual world. In an example, thecomputer vision techniques may be an image recognition task, a semanticsegmentation task, and the like. In a non-limiting example, theprocessor-based computer vision operation can include sequences offiltering operations, with each sequential filtering stage acting uponthe output of the previous filtering stage. For instance, when theprocessor (processing circuitry) is/includes a GPU, these filteringoperations are carried out by fragment programs.

In another example, the computer vision techniques may be aprocessor-based computer vision technique. In an embodiment, the firstdevice 701 can look for predetermined or repeatable patterns within theframe which indicates the presence of the reference patch. In anembodiment, the first device 701 can identify the reference patch basedon a confidence level, the confidence level being high when thepredetermined pattern of pixel luma and chroma manipulation and thepredetermined edging pattern of pixel luma and chroma manipulation aredetected in the reference patch. The confidence level can be lower whenone or neither of the predetermined patterns is/are detected.

According to an embodiment, in the event that an input to the operationis an image, the input images can be initialized as textures and thenmapped onto quadrilaterals. By displaying these quadrilaterals inappropriately sized windows, a one-to-one correspondence of image pixelsto output fragments can be ensured. Similarly, when the input to theoperation is an encoded image, a decoding process may be integrated intothe processing steps described above. A complete computer visionalgorithm can be created by implementing sequences of these filteringoperations. After the texture has been filtered by the fragment program,the resulting image is placed into texture memory, either by usingrender-to-texture extensions or by copying the frame buffer into texturememory. In this way, the output image becomes the input texture to thenext fragment program. This creates a pipeline that facilitates theentire computer vision algorithm. However, often a complete visionalgorithm may require operations beyond filtering. For example,summations are common operations. Furthermore, more-generalizedcalculations, such as feature tracking, can also be mapped effectivelyonto graphics hardware.

In an embodiment, the reference patch can be identified by use of edgedetection methods. In particular, edge detection can be used for theperimeter of the reference patch having a predetermined pattern (thepredetermined edging pattern). In an example, the edge detection methodmay be a Canny edge detector. The Canny edge detector may run on theGPU. In one instance, the Canny edge detector can be implemented as aseries of fragment programs, each performing a step of the algorithm.

In an embodiment, the identified reference patch can be tracked fromframe to frame using feature vectors. Calculating feature vectors atdetected feature points is an operation in computer vision. A feature inan image is a local area around a point with some higher-than-averageamount of uniqueness. This makes the point easier to recognize insubsequent frames of video. The uniqueness of the point is characterizedby computing a feature vector for each feature point. Feature vectorscan be used to recognize the same point in different images and can beextended to more generalized object recognition techniques.

Feature detection can be achieved using methods similar to the Cannyedge detector that instead search for corners rather than lines. If thefeature points are being detected using sequences of filtering, the GPUcan perform the filtering and read back to the CPU a buffer that flagswhich pixels are feature points. The CPU can then quickly scan thebuffer to locate each of the feature points, creating a list of imagelocations at which feature vectors on the GPU will be calculated.

In step 315, the first device 701 can decode the encoded data of theunique identifiers from the area of the reference patch, wherein theunique identifiers correspond to the surface area. The uniqueidentifiers can be hashed values that could have been generatedbeforehand by the first device 701.

In step 320, the first device 701 can use the unique identifiers to linkthe surface area with the digital content using metadata and retrievethe digital content based on the unique identifiers.

In step 325, the first device 701 can overlay the digital content ontothe surface area of the displayed data based on the unique identifiers.

Again, the method of identifying the reference patch included in thedisplayed data and augmenting the displayed data is described asperformed by the first device 701, however, the second device 850 caninstead perform the same functions.

In an embodiment, the first device 701 identifies the surface areacorresponding to the reference patch by employing further processes toprocess the frames. To this end, FIG. 3B is a flow chart of a sub-methodof identifying the reference patch with the unique identifierscorresponding to the surface area from the stream of data, according toan embodiment of the present disclosure.

In step 310 a, the first device 701 can decode the encoded referencepatch from the frame. The encoded reference patch can include the markerthat makes up the unique identifiers within the reference patchincorporated previously. The reference patch can also include otheridentifying information. The marker can be disposed within the referencepatch, such as within the area of the reference patch or along aperimeter of the reference patch, or alternatively, outside of the areaof the reference patch.

Whatever schema is used to encode the marker in the reference patch isalso used in reverse operation to decode the underlying informationcontained within the reference patch. As stated above, in an embodiment,the encoded marker can be patterns generated and decoded using the ARUCOalgorithm or by other algorithms that encode data according to apredetermined approach.

In step 310 b, the first device 701 can also extract attributes of thesurface area from the reference patch. In an embodiment, the position,size, shape, and perimeter of the surface area are extracted, althoughother parameters can be extracted as well. Other parameters includeboundary lines, area, angle, depth of field, distance, ratio of pairs ofpoints, or the like. In an embodiment, where shape and perimeter aredesignated as the attributes, the first device 701 makes determinationsof size, shape, and perimeter and outputs that result. Specifically, thesize or shape of the surface area can be determined by evaluating apredetermined or repeatable pattern of pixel luma and chromamanipulation in the reference patch. The predetermined pattern can bemarked on, within the area, or outside of the area of the referencepatch. The predetermined pattern can correspond to the size or shape ofthe surface area. The predetermined pattern can correspond to the sizeor shape of the digital content. The perimeter of the surface area canalso be determined by evaluating a predetermined edging pattern of pixelluma and chroma manipulation. The predetermined edging pattern can bemarked on, within the area, or outside of the area of the referencepatch. That is, the predetermined edging pattern of the refence patchcan correspond to the perimeter of the surface area. The predeterminededging pattern of the refence patch can correspond to the perimeter ofthe digital content.

In step 310 c, the first device 701 can also calculate a position andsize of the surface area relative to the size and shape (dimensions) ofthe output signal from the display that is displaying the displayeddata. In an embodiment, the calculating of the size, relative to thesize and shape of the outputted signal from the display, includesdetermining the size of the surface area by inspecting a furthestmeasured distance between the edges of the surface area. Furthermore,the calculating of a location of the surface area, relative to the sizeand shape of the outputted signal from the display, includes determiningthe location of the surface area relative to the size and shape of thedisplayed data outputted through the display. This includes calculatingthe distance between the outer edges of the surface area and the inneredges of the displayed data being outputted by the display. Thedetermined size and location of the surface area can be outputted as aresult. Notably, prior to overlaying the digital content into thedisplayed data, the first device 701 can adjust, based on thepredetermined pattern and the predetermined edging pattern, the size andperimeter of the digital content for displaying in the display of thefirst device 701. For example, the size and perimeter of the digitalcontent for displaying in the display of the first device 701 can bescaled based on the size and perimeter of the surface area and/or thesize of the display.

The first device 701 can provide information regarding thecharacteristics of the output video signal, such that the digitalcontent that is later overlaid can correctly be displayed to account forvarious manipulations or transformations that may take place due tohardware constraints, user interaction, image degradation, orapplication intervention. Such manipulations and transformations may bethe relocation, resizing, and scaling of the reference patch and/or thesurface area, although the manipulations and transformations are notlimited to those enumerated herein.

In an embodiment, the reference patch itself can be used as thereference for which the digital content is displayed on the surfacearea. In one example, the location at which to display the digitalcontent in the surface area can be determined relative to the locationof the reference patch on the displayed data. In one example, the sizeof the surface area can be determined relative to the size of thereference patch on the displayed data. In an example employing acombination of the two properties of the reference patch, the referencepatch displayed in the displayed data on a smart phone having apredetermined size and a surface area can be scaled relative to thepredetermined size of the display of the smart phone. This can befurther adjusted when the reference patch in the same displayed data isdisplayed on a desktop monitor, such that the predetermined size of thereference patch in the displayed data displayed on the desktop monitoris larger and thus the size of the surface area can be scaled to belarger as well. Furthermore, the location of the surface area can bedetermined via a function of the predetermined size of the referencepatch. For example, the location at which to display the digital contentin the surface area can be disposed some multiple widths laterally awayfrom the location of the reference patch as well as some multipleheights longitudinally away from the location of the reference patch. Assuch, the predetermined size of the reference patch can be a function ofthe size of the display of the first device 701. For example, thepredetermined size of the reference patch can be a percentage of thewidth and height of the display, and thus the location and the size ofthe surface area are also a function of the width and height of thedisplay of the first device 701.

In an embodiment, the first device 701 can determine an alternativelocation at which to display the digital content based on behaviors ofthe user. For example, the first device 701 can compare the encoded datacorresponding to the location at which to display the digital content inthe surface area to training data describing movement and focus of theuser's eyes while viewing the displayed data. Upon determining thelocation at which to display the digital content in the surface area (asencoded in the reference patch) is not the same as the training data,the first device 701 can instead display the digital content at thelocation described by the training data as being where the user's eyesare focused in the displayed data at a particular time. For example, theuser's eyes may be predisposed to viewing a bottom-right of a slide in aslide deck. The first device 701 can decode the reference patch anddetermine the digital content is to be displayed in a bottom-left of theslide deck. The training data can indicate that, for example, the user'seyes only focus on the bottom-left of the slide 10% of the time, whileuser's eyes focus on the bottom-right of the slide 75% of the time.Thus, the first device 701 can then display the digital content in thebottom-right of the slide instead of the bottom-left. The training datacan also be based on more than one user, such as a test populationviewing a draft of the slide deck. For example, the training data can bebased on multiple presentations of the slide deck given to multipleaudiences, wherein eye tracking software determines the average locationof the audience's focus on each of the slides.

In an embodiment, the first device 701 employs other processes toassociate the unique identifiers with the digital content. To this end,FIG. 3C is a flow chart of a sub-method of associating the uniqueidentifiers with digital content, according to an embodiment of thepresent disclosure. In step 320 a, the first device 701 can send theunique identifiers to the second device 850 and the second device 850can retrieve metadata that describes the digital content, the digitalcontent being associated with the surface area through the uniqueidentifiers. This can be done by querying a remote location, such as adatabase or a repository, using the unique identifiers of the surfacearea as the query key. In an embodiment, the first device 701 sends theunique identifiers to the second device 850 and the second device 850associates the unique identifier of the reference patch to correspondingdigital content based on the metadata. The metadata associated with thesurface area's unique identifier can be transmitted to the first device701 with the augmentation content.

In step 320 b, the first device 701 can assemble the digital contentthat is associated with the surface area's unique identifier. Theassembly can entail loading the necessary assets for assembling thedigital content. In an embodiment, this can entail loading manipulationsoftware or drivers in order to enable the first device 701 to processthe digital content. Other assembling processes can be the loading ofrendering information in order to transform and manipulate an individualportion of the digital content. Furthermore, the loaded manipulationsoftware, drivers, or rendering information can be used to compile allthe individual portions of the entire digital content together. In anembodiment, this can include adapting the file formats of the digitalcontent, delaying the playback for the digital content, converting fromone format to another, scaling the resolution up or down, converting thecolor space, etc.

In step 320 c, the first device 701 can provide access controlparameters for the digital content. The access control parameters candictate whether the digital content is visible to some users, or to somegeographical locations, or to some types of displays and not others, aswell as the date and time or duration of time a user can access thedigital content or is allowed to access. In an embodiment, visibility ofthe digital content can be defined for an individual. For example, thedigital content can be a video that is appropriate for users over acertain age. In an embodiment, visibility of the digital content can bedefined for a geographic location. For example, the digital content canbe a video that is region-locked based on a location of the first device701. In an embodiment, visibility of the digital content can be definedfor a type of display displaying the displayed data. For example, thedigital content can be VR-based and will only display with a VR headset.In an embodiment, visibility of the digital content can be defined for apredetermined date and a predetermined time. For example, the digitalcontent can be a video that will only be made publicly available after apredetermined date and a predetermined time. In an embodiment,visibility of the digital content can be defined for a time period. Forexample, the digital content can be a video that is only available forviewing during a holiday. The first device 701 thus calculates theuser's access level based on those parameters and provides an outputresult as to the user's ability to access the digital content, i.e.,whether the digital content will be visible or invisible to the user.Note that the access control parameters can be global, for all thedisplayed data, or it can be localized per surface area and theunderlying digital content.

Referring again to FIG. 3A, in step 325, the first device 701 can carryon the processes of overlaying the surface area with the digital contentinto the displayed data in accordance with the surface area, theposition, and the size identified by the unique identifier. The firstdevice 701 can determine or adjust the size and location of theassembled digital content on the surface area relative to the size andshape of the displayed data being outputted by the display. Then, thefirst device 701 can render the associated digital content (or theassembled individual portions) over the surface area's shape andperimeter using the size and location information. Thus, the digitalcontent is superimposed on top of the surface area.

The first device 701 can continuously monitor changes that are takingplace at the end user's device (such as the second device 702 of thesecond user) to determine whether the reference patch and/or the surfacearea has moved or been transformed in any way. Thus, the first device701 can continuously inspect subsequent frames of the stream of the data(for example, every 1 ms or by reviewing every new frame), displayingthe displayed data, to determine these changes. The first device 701 canfurther continuously decode the reference patch's data from theidentified reference patch. Then the first device 701 can continuouslyextract attributes from the data, the attributes being of size, shape,and perimeter and comparing those changes between the current frame andlast frame. Further, the first device 701 can continuously calculate thesize and location of the surface area and compare changes between thesize and location of the surface area from the current and the lastframe and then continuously overlay the digital content on the surfacearea by incorporating the changes in the reference patch's attributesand the changes in the size and location of the surface area. As statedabove, when the user manipulates his/her display device by scaling,rotating, resizing or even shifting the views from one display deviceand onto another display device, the first device 701 can track thesechanges and ensure that the digital content is properly beingsuperimposed onto the surface area.

An illustrative example will now be discussed: a scenario where a user(for example, a user at the first device 701) receives (from anotherdevice such as the third device 702) an email with the embeddedreference patch in the body of the email or as an attached document. Thereference patch within the displayed data (email) can show a facade ofthe digital content or the reference patch. The application on the firstdevice 701 can scan the display to find the reference patch and thesurface area and the attributes within the displayed data as it is beingdisplayed. Furthermore, the first device 701 can access the digitalcontent using the unique identifier and metadata and prepare it foroverlaying. At which point, the user (i.e., the recipient) can selectthe digital content by various ways such as by clicking on the digitalcontent's facade or the surface area, or otherwise indicating that itintends to access the digital content.

Thereafter, the digital content can be retrieved from the second device850 using the unique identifier and the metadata saved within a databasethat directs the second device 850 to where the digital content is savedand can be obtained. That is, the second device 850 can determine thedigital content corresponding to the derived unique identifier and sendthe digital content corresponding to the unique identifier (and themetadata) to the first device 701. Then, the first device 701 cansuperimpose (overlay) the digital content on the surface area. While thedigital content is being received and overlayed on the surface area, thefirst device 701 can continually monitor the location, size and/or shapeof the reference patch and/or the surface area to determine movement andtransformation of the reference patch and/or the surface area. If theuser has moved the location of the reference patch and/or the surfacearea, or has resized or manipulated the screen for whatever purpose, thenew location, shape and/or size information of the reference patchand/or the surface area is determined in order to display the digitalcontent properly within the bounds of the surface area. Thus, thedigital content moves with the displayed data as the displayed data ismoved or resized or manipulated.

In an embodiment, a user that has received the displayed data embeddedwith the reference patch can access the digital content on his/her firstdevice 701, as described above. The user may want to transfer theongoing augmenting experience from the first device 701 to anotherdevice, such as the device 70 n, in a seamless fashion. In thatscenario, the user is able to continue the augmenting experience onhis/her smartphone, smartwatch, laptop computer, display connected witha webcam, and/or tablet pc. The user therefore can capture the embeddedreference patch and therefore the encoded attributes, as the digitalcontent is being accessed and overlaid unto the surface area. The usercan capture the embedded reference patch by taking a picture of it oracquiring the visual information using a camera of the third device 702as mentioned above.

Assuming the user also has the functionality included or the applicationinstalled or running on the device 70 n, the device 70 n would recognizethat an embedded reference patch and encoded unique identifiers are inthe captured image/video stream. Once the surface area has beendetermined and the reference patch decoded, the digital content can beobtained from the second device 850, using the unique identifiers andthe metadata and then overlaid on the surface area within the displayeddata displayed on the device 70 n. In an embodiment, as soon as thedevice 70 n superimposes the digital content onto the surface area, thesecond device 850 or the backend determines that the stream has now beenredirected onto the device 70 n and thus pushes a signal to the firstdevice 701 to stop playing the digital content on the first device 701.The device 70 n that is overlaying the digital content therefore resumesthe overlaying at the very same point that the first device 701 stoppedoverlaying the digital content (for instance, when the content is avideo for example). Thus, the user is able to handoff the digitalcontent from one device to another without noticing delay or disruptionin the augmenting experience.

In another illustrative example of content augmentation, the user can bebrowsing a page of a website. The webpage may be dedicated todiscussions of strategy in fantasy football, a popular online sportsgame where users manage their own rosters of football players and pointsare awarded to each team based on individual performances from eachfootball player on the team. After reading the discussion on the websitepage, the user may wish to update his/her roster of football players.Traditionally, the user would be required to open a new window and/or anew tab and then navigate to his/her respective fantasy footballapplication, to his/her team, and only then may the user be able tomodify his/her team. Such a digital user experience can be cumbersome.With augmentation, however, the user may not need to leave the originalwebpage since a reference patch corresponding to a fantasy footballaugmentation (i.e., fantasy football digital content for overlaying onthe displayed website page) may be positioned within the viewable areaof the website page. The corresponding digital content may be, forinstance, an interactive window provided by a third-party fantasyfootball application that allows the user to modify his/her rosterwithout leaving the original web site. Thus, instead of navigating to adifferent web site and losing view of the informative fantasy footballdiscussion, the user can simply interact with the digital content thatis being overlaid on the displayed data.

In yet another illustrative example of content augmentation, as will bedescribed with reference to FIG. 4A through FIG. 4C, the displayed datais a slide deck. The slide deck may be generated by a concierge-typeservice that seeks to connect a client with potential garden designers.As in FIG. 4A, the slide deck may be presented to the client within aviewable area 103 of a display 102 of the first device 701. Thepresently viewable content of the slide deck within the viewable area103 of the display 102 may be a current frame of display data 106.Traditionally, the slide deck may include information regarding eachpotential garden designer and may direct the client to third-partyapplications that allow the client to contact each designer. In otherwords, in order to connect with one or more of the potential gardendesigners, the client, traditionally, may need to exit the presentationand navigate to a separate internet web browser in order to learn moreabout the garden designers and connect with them. Such a digital userexperience can be also cumbersome.

With augmentation, however, the client need not leave the presentationin order to set up connections with the garden designers. For instance,as shown in FIG. 4B, a reference patch 104 can be positioned within theslide deck to be in the current frame 106 and viewable within theviewable area 103 of the display 102 at an appropriate moment. As shownin FIG. 4C, the reference patch 104 may correspond to digital content105 (i.e., one or more augmentations) and, when the reference patch 104is visible to/detectable by the first device 701, the digital content105 is retrieved and displayed by the first device 701 at thecorresponding surface area. The digital content 105 can include, asshown in FIG. 4C, interactive buttons, images, videos, windows, andicons, among others, that allow the client to interact with thedisplayed data and to, for instance, engage with the garden designerswithout leaving the presentation. In an example, the interactive digitalcontent 105 may allow for scheduling an appointment with a given gardendesigner while still within the slide deck.

As previously noted, the above-described augmentations are particularlyrelevant to environments where the underlying content is static. Staticcontent may include textual documents or slide decks. Often, the staticcontent is stored locally in the electronic device. Due to its nature,the static content is not capable of being dynamically adjustedaccording to complex user interactions, in real-time, during the userexperience.

Such a dynamic environment includes one where, for instance, a videoconversation is occurring. A first participant of the video conversationmay share their screen with a second participant of the videoconversation and wish to remotely-control the digital content on adisplay of a device of the second participant. By including thereference patch within the displayed data that is being shared, whichmay be the video itself or another digital item, where sharing thedisplayed data includes transmitting the displayed data over acommunication network from the first participant to the secondparticipant, the second participant may be able to experience thedigital content when the device of the second participant receives thetransmitted displayed data and processes it for display to the user.

Generally, and as introduced in the above example of a dynamicenvironment, the reference patch 104 can be inserted into displayed datadisplayed on a first computer or the first device 701. The display ofthe first device 701 can be streamed to a second computer or the thirddevice 702. In an example, the third device 702 decodes the streameddisplay of the first device 701 and, based on the identified presence ofthe reference patch 104, can locally-augment the display of the thirddevice 702 to overlay the intended digital content on the streameddisplay of the first device 701. The design and the arrangement of thedigital content can be provided relative to the reference patch 104placed into the displayed data on the first device 701. The digitalcontent can include objects to be displayed and may be configured todisplay different subsets of objects based on interactions of a userwith the digital content. The objects, therefore, may be interactive.

In an example of a live video stream, a user may be a yoga instructorteaching a remote yoga class by Microsoft Teams. Each participant in theclass may be able to view the yoga instructor via their respectivedevices, wherein the ‘live streamed’ video includes video of the yogainstructor guiding the participants of the class through the techniques.At the end of class, the yoga instructor may wish to receive paymentfrom each of the participants. The instructor may open a cloud-basedslide which, for instance, may have the reference patch 104, therein.The reference patch 104 may be configured to augment a pay buttonrelative to a position of the reference patch 104 on a device display ofeach participant. Upon screen sharing the cloud-based slide with theparticipants in the class, each participant's device receives thetransmitted displayed data and processes the displayed data for display.During processing, each device observes and identifies the referencepatch 104 within the displayed data. Accordingly, each device cangenerate a local augmentation (i.e., retrieve and display thecorresponding digital content) on a respective display in order for theparticipant to be able to enter the payment information and pay for theremote yoga class. The digital content may be generated within the livevideo stream.

In another example of a live video stream, and as will be described withreference to FIG. 5A through FIG. 5K, a user may be a bank tellerdiscussing a new savings account with a potential bank member. The bankteller may initiate a video call with the potential bank member. Thebank teller may include, within a video stream being transmitted fromthe bank teller to the potential bank member, the reference patch 104.The transmitted video stream may include a video feed generated by acamera associated with a device (the first device 701) of the bankteller. Accordingly, the transmitted video stream may include an imageof, for instance, a face of the bank teller and the reference patch 104therein. Upon receiving the video stream, a device of the potential bankmember (the third device 702) may process the video stream and identifythe reference patch 104. Accordingly, the third device 702 of thepotential bank member may generate a local augmentation (i.e., retrieveand display the corresponding digital content) on the respective displayof the third device 702 in order to allow the potential bank member tobe able to interact with the bank teller and establish the new savingsaccount. The digital content may appear on top of the live video streamof the bank teller. The digital content can include a number of objectsto be displayed and may be configured to display different subsets ofobjects based on interactions of a user with the digital content, theobjects being interactive in some cases. This allows for the digitalcontent to be updated in response to user interactions.

For instance, updated digital content may reflect a step by step processof opening the new savings account, the digital content being updated ateach step according to the interactions of the potential bank member.First, the digital content may require confirmation of identity, whichcan include instructing the potential bank member in exhibiting his/herdriver's license such that an image of the driver's license can beobtained. The confirmation of identity may also include instructionrelated to and acquisition of an image of the potential bank member.Next, the digital content may present a banking contract to thepotential bank member, the potential bank member then being able toreview and sign the banking contract. Lastly, the digital content canrequest the potential bank member provide verbal confirmation of theapproval of the bank contract. Each of these steps can be associatedwith a same reference patch 104 corresponding to digital content thatguides the ‘new’ bank member along the account setup process.

With reference now to FIG. 5A through FIG. 5K, an exemplaryimplementation of a live stream video augmentation will be described inmore detail. In the exemplary implementation, a bank teller 521 (e.g.,on the first device 701) discusses a new savings account with apotential bank member 531 (e.g., on the third device 702). The bankteller 521 may initiate the video call with the potential bank member531. The bank teller 521 may include, within a video stream beingtransmitted from the bank teller to the potential bank member 531, thereference patch 104. In the example of FIG. 5A, the reference patch 104is a bank logo (in this case, a Chase logo). The transmitted videostream may include a video feed 506 generated by a camera associatedwith the first device 701 of the bank teller 521. Accordingly, thetransmitted video stream may include an image of, for instance, a faceof the bank teller 521 and the reference patch 104 therein. Uponreceiving the video stream, the third device 702 of the potential bankmember 531 may process the video stream and identify the reference patch104 within this video stream.

Accordingly, the third device 702 of the potential bank member 531 mayobtain rendering instructions for digital content 541 (i.e., anaugmentation) corresponding to the reference patch 104 and then retrieveand display the digital content 541 at/on the surface area on arespective display of the third device 702 in order to allow thepotential bank member 531 to be able to interact with the bank teller521 and establish the new savings account. The digital content 541 maybe generated on top of the live video stream 506 of the bank teller 521.The digital content 541 can include a number of objects 551 to bedisplayed and may be configured to display different subsets of objectsbased on interactions of the potential bank member 531 with the digitalcontent 541, the objects 551 being interactive in some cases. Thisallows for the digital content 541 to be updated in response to userinteractions. Note that the digital content can be retrieved from aserver such as the second device 850.

For instance, updated digital content may reflect the step by stepprocess of opening the new savings account, the digital content beingupdated at each step according to the interactions of the potential bankmember. With reference to FIG. 5B through FIG. 5D, the digital content541 may first require confirmation of the identity of the potential bankmember 531. This can include instructing the potential bank member 531to exhibit his/her driver's license such that an image of the driver'slicense can be obtained. As shown in FIG. 5C, a guide can be deployedand a confirmation graphic can be displayed, as in FIG. 5D, when anadequate image of the driver's license has been obtained. Theconfirmation of identity may also include instruction related to andacquisition of an image of the potential bank member 531. Next, thedigital content 541 may present a banking contract 561 to the potentialbank member 531, as shown in FIG. 5E. As shown in the FIG. 5F, thepotential bank member 531 may then review and provide a signature 562 ifthe banking contract 561 is approved. Lastly, the digital content 541can request the potential bank member 531 to provide verbal confirmationof the approval of the banking contract 561.

As shown in FIG. 5G, the potential bank member 531 may be prompted witha transcript that is to be read back and recorded via the digitalcontent 541 to confirm the approval of the potential bank member 531. Asshown in FIG. 5H and FIG. SI, the potential bank member 531 mayinstructed by a countdown and an indication of live recording. FIG. 5Jillustrates an aspect of the digital content 541 that allows thepotential bank member 531 to review the recorded spoken transcriptapproving the bank contract 561. Once completed, as shown in FIG. 5K,the digital content 541 can display a congratulatory graphic and welcomethe newest member of the bank. Each of these steps can be associatedwith a same reference patch corresponding to digital content that guidesthe new bank member along the account setup process via the third device702.

According to an embodiment, the above examples allow for live streamingof data from one device to another (or many others), where frames of thedata stream include the reference patch. The data stream could be adisplay of a cloud-based slide within a live video, a webcam feed, orother similar data source. The streamed reference patch can berecognized by (processing circuitry of) the first device 701 receivingthe data stream and can initiate retrieval and displaying of digitalcontent associated with the reference patch. Device(s) receiving thestreamed data, which may be a screen share, a live webcam feed, and thelike, can then render the digital content locally on the device(s).

Further to the above, the reference patch may be used to generatedigital content for a variety of implementations. Such implementationscan include renewing a motor vehicle driver's license, signing acontract, obtaining a notarization from a notary public, renewing atravel document, and the like.

It can be appreciated that the present disclosure is not limited to theabove-described examples. In these examples, the user of the firstdevice 701 may act in a manner of remote control. In one instance, theyoga instructor can remotely control an experience for his/her students.In another instance, the bank teller can remotely control an experiencefor the new account owner. In the instance of the yoga instructor, theremote control is provided between many devices, where the yogainstructor is able to control an experience of a plurality ofparticipants from a single first device 701. However, in the instance ofthe bank teller, the remote control is provided between only twodevices, where the bank teller is able to control the display of the newaccount owner.

In an embodiment, there may be synchronized experiences between only twodevices and/or a synchronized experience from one device to manydevices. For example, two individuals may play chess over live video ofthe competitor. This is a synchronized experience between only twodevices. Similarly, five friends may watch a live football game onseparate devices, where the betting experience digital content (e.g.,DraftKings, etc.) is overlaid on each of their devices. A synchronizedexperience may be shared amongst the devices. In other words, this is asynchronized experience from one device to many devices, wherein the onedevice is generated by the host of the football game stream.

According to an embodiment, the reference patch can be inserted into, aspart of the displayed data, recorded video that is to be displayed onthe first device 701. In an example, the first device 701 decodes therecorded video and, based on the identified presence of the referencepatch, can locally-augment the display of the first device 701 tooverlay the intended digital content on the recorded video. The designand the arrangement of the digital content can be provided relative tothe reference patch placed into the displayed data. The reference patchmay be placed into the displayed data, or recorded video, by theoriginal content creator or by another party that wishes to enhance theuser visual experience.

In an example, a music video having the reference patch may be playedover a video player (e.g., Vimeo) by a fan. The reference patch mayretrieve and display digital content that makes it possible for the fanto purchase tickets to the artist's next live concert that is within apredefined radius of a current address, home address, or other addressassociated with the fan. Here, the live concerts that are loaded in thedigital content over the music video, that is being played over thevideo player, is personalized to each fan and their respective location.The reference patch allows the live concert data to be loaded in realtime.

In another example, a recorded educational video from, for instance,Khan Academy can have the reference patch that triggers a quiz for astudent watching the video. In this way, the video can be paused whilethe digital content is rendered, and the student completes the quizwithin the digital content. Once the quiz has been completed, thestudent may proceed to the next segment of the video.

In the above recorded video examples, the reference patch can be placedwithin recorded streams of data. A decoder present at the end userdevice can be used to identify the reference patch and then locallyaugment the display of the end user device to allow for dynamic userinteraction with the digital content of the recorded video.

In an embodiment, the digital content can be the same for all viewers ofthe recorded video. In an embodiment, the digital content may bepersonalized for each viewer of the recorded video. The digital contentcan be live and updated in real time (or at the same time scale as therecorded video). The digital content can be attended or non-attended. Inother words, a version of the educational video may have a teacher liveremote controlling the experience.

In an embodiment, a plurality of the reference patches can be includedin the displayed data. That is, the display of the first device 701 neednot only display just one of the reference patches on the display at anygiven time. For example, the slide deck can include three refencepatches on a single slide that is being displayed in the displayed data.Each reference patch of the three reference patches can be detected andprocessed by the first user device 701. In an embodiment, the multiplereference patches can have a priority for displaying the correspondingdigital content on the displayed data. The priority can be based on adetermined theme of the displayed data detected by the first device 701,or based on an assigned priority value, or a combination thereof, amongothers. For example, a first reference patch can be an area of theuser's face in an image of the user in a slide and have the highestpriority, a second reference patch can be an area of a logo of a companyemploying the user in the slide and have the second-highest priority (bythe user device 701), and a third reference patch can be thebottom-right area of the slide and have the third-highest priority. Thehighest priority of the first reference patch can be assigned to alwayshave the highest priority, while the second reference patch and thethird reference patch can have priorities that are not assigned and thusdetermined by the user device 701 based on a relation to content in thedisplayed data.

Electronic device 600 shown in FIG. 6 can be an example of one or moreof the devices shown in FIG. 1. In an embodiment, the device 600 may bea smartphone. However, the skilled artisan will appreciate that thefeatures described herein may be adapted to be implemented on otherdevices (e.g., a laptop, a tablet, a server, an e-reader, a camera, anavigation device, etc.). The device 600 of FIG. 6 includes processingcircuitry, as discussed above. The processing circuitry includes one ormore of the elements discussed next with reference to FIG. 6. The device600 may include other components not explicitly illustrated in FIG. 6such as a CPU, GPU, frame buffer, etc. The device 600 includes acontroller 610 and a wireless communication processor 602 connected toan antenna 601. A speaker 604 and a microphone 605 are connected to avoice processor 603.

The controller 610 may include one or more processors/processingcircuitry (CPU, GPU, or other circuitry) and may control each element inthe device 600 to perform functions related to communication control,audio signal processing, graphics processing, control for the audiosignal processing, still and moving image processing and control, andother kinds of signal processing. The controller 610 may perform thesefunctions by executing instructions stored in a memory 650.Alternatively, or in addition to the local storage of the memory 650,the functions may be executed using instructions stored on an externaldevice accessed on a network or on a non-transitory computer readablemedium.

The memory 650 includes but is not limited to Read Only Memory (ROM),Random Access Memory (RAM), or a memory array including a combination ofvolatile and non-volatile memory units. The memory 650 may be utilizedas working memory by the controller 610 while executing the processesand algorithms of the present disclosure. Additionally, the memory 650may be used for long-term storage, e.g., of image data and informationrelated thereto.

The device 600 includes a control line CL and data line DL as internalcommunication bus lines. Control data to/from the controller 610 may betransmitted through the control line CL. The data line DL may be usedfor transmission of voice data, display data, etc.

The antenna 601 transmits/receives electromagnetic wave signals betweenbase stations for performing radio-based communication, such as thevarious forms of cellular telephone communication. The wirelesscommunication processor 602 controls the communication performed betweenthe device 600 and other external devices via the antenna 601. Forexample, the wireless communication processor 602 may controlcommunication between base stations for cellular phone communication.

The speaker 604 emits an audio signal corresponding to audio datasupplied from the voice processor 603. The microphone 605 detectssurrounding audio and converts the detected audio into an audio signal.The audio signal may then be output to the voice processor 603 forfurther processing. The voice processor 603 demodulates and/or decodesthe audio data read from the memory 650 or audio data received by thewireless communication processor 602 and/or a short-distance wirelesscommunication processor 607. Additionally, the voice processor 603 maydecode audio signals obtained by the microphone 605.

The exemplary device 600 may also include a display 620, a touch panel630, an operation key 640, and a short-distance communication processor607 connected to an antenna 606. The display 620 may be an LCD, anorganic electroluminescence display panel, or another display screentechnology. In addition to displaying still and moving image data, thedisplay 620 may display operational inputs, such as numbers or iconswhich may be used for control of the device 600. The display 620 mayadditionally display a GUI for a user to control aspects of the device600 and/or other devices. Further, the display 620 may displaycharacters and images received by the device 600 and/or stored in thememory 650 or accessed from an external device on a network. Forexample, the device 600 may access a network such as the Internet anddisplay text and/or images transmitted from a Web server.

The touch panel 630 may include a physical touch panel display screenand a touch panel driver. The touch panel 630 may include one or moretouch sensors for detecting an input operation on an operation surfaceof the touch panel display screen. The touch panel 630 also detects atouch shape and a touch area. Used herein, the phrase “touch operation”refers to an input operation performed by touching an operation surfaceof the touch panel display with an instruction object, such as a finger,thumb, or stylus-type instrument. In the case where a stylus or the likeis used in a touch operation, the stylus may include a conductivematerial at least at the tip of the stylus such that the sensorsincluded in the touch panel 630 may detect when the stylusapproaches/contacts the operation surface of the touch panel display(similar to the case in which a finger is used for the touch operation).

In certain aspects of the present disclosure, the touch panel 630 may bedisposed adjacent to the display 620 (e.g., laminated) or may be formedintegrally with the display 620. For simplicity, the present disclosureassumes the touch panel 630 is formed integrally with the display 620and therefore, examples discussed herein may describe touch operationsbeing performed on the surface of the display 620 rather than the touchpanel 630. However, the skilled artisan will appreciate that this is notlimiting.

For simplicity, the present disclosure assumes the touch panel 630 is acapacitance-type touch panel technology. However, it should beappreciated that aspects of the present disclosure may easily be appliedto other touch panel types (e.g., resistance-type touch panels) withalternate structures. In certain aspects of the present disclosure, thetouch panel 630 may include transparent electrode touch sensors arrangedin the X-Y direction on the surface of transparent sensor glass.

The touch panel driver may be included in the touch panel 630 forcontrol processing related to the touch panel 630, such as scanningcontrol. For example, the touch panel driver may scan each sensor in anelectrostatic capacitance transparent electrode pattern in theX-direction and Y-direction and detect the electrostatic capacitancevalue of each sensor to determine when a touch operation is performed.The touch panel driver may output a coordinate and correspondingelectrostatic capacitance value for each sensor. The touch panel drivermay also output a sensor identifier that may be mapped to a coordinateon the touch panel display screen. Additionally, the touch panel driverand touch panel sensors may detect when an instruction object, such as afinger is within a predetermined distance from an operation surface ofthe touch panel display screen. That is, the instruction object does notnecessarily need to directly contact the operation surface of the touchpanel display screen for touch sensors to detect the instruction objectand perform processing described herein. For example, in an embodiment,the touch panel 630 may detect a position of a user's finger around anedge of the display panel 620 (e.g., gripping a protective case thatsurrounds the display/touch panel). Signals may be transmitted by thetouch panel driver, e.g., in response to a detection of a touchoperation, in response to a query from another element based on timeddata exchange, etc.

The touch panel 630 and the display 620 may be surrounded by aprotective casing, which may also enclose the other elements included inthe device 600. In an embodiment, a position of the user's fingers onthe protective casing (but not directly on the surface of the display620) may be detected by the touch panel 630 sensors. Accordingly, thecontroller 610 may perform display control processing described hereinbased on the detected position of the user's fingers gripping thecasing. For example, an element in an interface may be moved to a newlocation within the interface (e.g., closer to one or more of thefingers) based on the detected finger position.

Further, in an embodiment, the controller 610 may be configured todetect which hand is holding the device 600, based on the detectedfinger position. For example, the touch panel 630 sensors may detect aplurality of fingers on the left side of the device 600 (e.g., on anedge of the display 620 or on the protective casing), and detect asingle finger on the right side of the device 600. In this exemplaryscenario, the controller 610 may determine that the user is holding thedevice 600 with his/her right hand because the detected grip patterncorresponds to an expected pattern when the device 600 is held only withthe right hand.

The operation key 640 may include one or more buttons or similarexternal control elements, which may generate an operation signal basedon a detected input by the user. In addition to outputs from the touchpanel 630, these operation signals may be supplied to the controller 610for performing related processing and control. In certain aspects of thepresent disclosure, the processing and/or functions associated withexternal buttons and the like may be performed by the controller 610 inresponse to an input operation on the touch panel 630 display screenrather than the external button, key, etc. In this way, external buttonson the device 600 may be eliminated in lieu of performing inputs viatouch operations, thereby improving watertightness.

The antenna 606 may transmit/receive electromagnetic wave signalsto/from other external apparatuses, and the short-distance wirelesscommunication processor 607 may control the wireless communicationperformed between the other external apparatuses. Bluetooth, IEEE802.11, and near-field communication (NFC) are non-limiting examples ofwireless communication protocols that may be used for inter-devicecommunication via the short-distance wireless communication processor607.

The device 600 may include a motion sensor 608. The motion sensor 608may detect features of motion (i.e., one or more movements) of thedevice 600. For example, the motion sensor 608 may include anaccelerometer to detect acceleration, a gyroscope to detect angularvelocity, a geomagnetic sensor to detect direction, a geo-locationsensor to detect location, etc., or a combination thereof to detectmotion of the device 600. In an embodiment, the motion sensor 608 maygenerate a detection signal that includes data representing the detectedmotion. For example, the motion sensor 608 may determine a number ofdistinct movements in a motion (e.g., from start of the series ofmovements to the stop, within a predetermined time interval, etc.), anumber of physical shocks on the device 600 (e.g., a jarring, hitting,etc., of the electronic device), a speed and/or acceleration of themotion (instantaneous and/or temporal), or other motion features. Thedetected motion features may be included in the generated detectionsignal. The detection signal may be transmitted, e.g., to the controller610, whereby further processing may be performed based on data includedin the detection signal. The motion sensor 608 can work in conjunctionwith a Global Positioning System (GPS) section 660. The information ofthe present position detected by the GPS section 660 is transmitted tothe controller 610. An antenna 661 is connected to the GPS section 660for receiving and transmitting signals to and from a GPS satellite.

The device 600 may include a camera section 609, which includes a lensand shutter for capturing photographs of the surroundings around thedevice 600. In an embodiment, the camera section 609 capturessurroundings of an opposite side of the device 600 from the user. Theimages of the captured photographs can be displayed on the display panel620. A memory section saves the captured photographs. The memory sectionmay reside within the camera section 609 or it may be part of the memory650. The camera section 609 can be a separate feature attached to thedevice 600 or it can be a built-in camera feature.
